Birkenstock has a great insert...at least they used to have one. My pain was so bad one day and I happened to be parked in front of the Birkenstock store so I went in. They put that insert in my shoe and it instantly took the pressure off of my heel. I told the guy, "I will pay whatever it takes to have these." I don't remember how much they were but it was worth if. Wore them for years and years until I had some especially made for me. They were a God send, an answer to all my foot problems. Don't konw if they still have them or not.
